Problems solved by technology

Although halides have excellent flame retardant properties, they have been proven to emit toxic and harmful hydrogen halides, polybrominated dibenzodioxins and furan gases when burned at high temperatures, which will cause environmental pollution and human injury. There are strict restrictions on it in the field of transportation
Thirdly, the preparation process of resin glue for laminated products often requires medium temperature and constant temperature reaction to the resin glue due to the poor miscibility between various raw materials and the high requirements of the prepreg preparation process. high equipment requirements

Abstract

The invention discloses an energy storage module insulation support member and a preparation method thereof. The energy storage module insulation support member is a composite material obtained by performing compression molding on an overlapping high-strength halogen-free flame-retardant resin glass fiber yarn prepreg at 140 to 175 DEG C. The preparation method comprises the following steps: preparing a high-strength halogen-free flame retardant resin adhesive, preparing a high-strength halogen-free flame retardant resin glass fiber yarn prepreg, and performing hot pressing forming to obtain the energy storage module insulation support member. The energy storage module insulation support member has a bending strength more than or equal to 500 MPa at normal temperature, a bending strength more than or equal to 250 MPa at 155 DEG C, a vertical layer electrical strength more than or equal to 10 KV / mm in a transformer oil of 90 DEG C, an insulation resistance more than or equal to 1.0 is multiplied by 10<7>M Omega after immersion in water for 24 hours, and an arc resistance of 182 to 186s. The halogen-free flame retardance reaches UL94V-0, and the member is especially suitable for a supercapacitor power system of an energy storage type tramcar.

Description

technical field [0001] The invention belongs to an insulating support for an energy storage module, and relates to an insulating support for an energy storage module and a preparation method thereof. The insulating support for an energy storage module of the invention is particularly suitable for use in an energy storage type tram supercapacitor power supply system. Background technique [0002] In recent years, trams are developing rapidly by virtue of advantages such as low construction cost, short construction period and long operation time. Among them, energy storage trams have become an important development trend of modern new urban trams due to their fast charging, large transport capacity, fast speed, reliable operation, and environmental protection. The insulating support for the energy storage power module will be mainly used as the insulating support for the supercapacitor in the world's first energy storage electric traction light rail train independently develop...
